Quick hookup and testing
If you would like to quick hookup the power inverter and check its performance before going ahead with your installation, please follow these guidelines:
1. Unpack and inspect the power inverter, check to see that the power switch in the OFF position.
2. Connect the cables to the power input terminals on the rear panel of power inverter. The red terminal is positive (+) and black terminal is negative (-). Connect the cables into the terminals and tighten the wing nut to clamp the wires securely.
3. Connect the cable from the negative terminal of the inverter to the negative terminal of the power source.
Make a secure connection.
CAUTION!!
Loosely tightened connectors result in excessive drop and may cause overheated wires and melted insulation.
4. Before proceed further, carefully check that cable you have just connected connects from the negative terminal of inverter to the negative output terminal of the power source.
CAUTION!!
Reverse polarity connection will blow fuse in inverter. Damage caused by reverse polarity connection is not covered by our warranty.
5. Connect the cable from the positive terminal of inverter to the positive terminal of the power source.
Make secure connection.
WARNING!!
You may observe a spark when you make this connection since current may flow to charge capacitors in the power inverter. Do not make this connection in the presence of flammable materials, explosions or fire may result.
6. Set the power switch to the ON position. Check the meters and indicators on the front panel of the inverter.
The voltage bar graph should indicate 11 to 14 volts (22 to 28V when 24V version is used) depending on the voltage of the power source.
If does not, check your power source and the connections to inverter. The other indicators should be off.
7. Set power inverter switch to the OFF position, the indicator lights may blink and the internal alarm may sound momentarily. This is normal.
8. Set power inverter switch to the ON position, then the inverter should supply power to the load. After that, turn the test load on.
Installation
1. Where to install
The power inverter should be installed in a location that meets the following requirements: a. Dry - Do not allow water to drip or splash on the inverter.
b. Cool - Ambient air temperature should be between
0 °C and 40 °C, the cool, the better.
c. Ventilated - Allow at least one inch of clearance around the inverter for airflow. Ensure the ventilation openings on the rear and bottom of the unit are not obstructed.
d. Safe - Do not install the inverter in the same compartment as batteries or in any compartment capable of storing flammable liquids such as gasoline.
2. Cables
DC to AC inverters requires high amperage/low voltage DC power to low amperage/high voltage AC power. To operate properly connect inverter DC input terminals direct to battery with heaviest wire available see chart below:

3. Grounding
The power inverter has a lug on the rear panel
"chassis ground". This is to connect the chassis of the power inverter to the ground. The ground terminals in the AC outlets on the front panel of the inverter are also connected to the ground lug.
The chassis ground lug must be connected to a grounding point, which will vary depending on where the power inverter is installed. In a vehicle, connect the chassis ground to the chassis of the vehicle. In a boat, connect to the boat's grounding systems. In a fixed location, connect the chassis ground lug to earth.
The neutral (common) conductor of the power inverter AC output circuit is connected to the chassis ground. Therefore, when the chassis is connected to ground, the neutral conductor will also be grounded. This conforms to national electrical code requirements that separately derived AC sources (such as inverters and generators) have their neutral tied to ground in the same way that the neutral conductor from the utility line is tied to ground at AC breaker panel.
!
The negative DC input of the power inverter is connected to the chassis. Do not install the power inverter in a positive ground DC system.
A positive ground DC system has the positive terminal of the battery connected to the chassis of the vehicle or to the grounding point.
!
Do not operate the power inverter without connecting it to ground. Electrical shock hazard may result.
Operation
To operate the power inverter, turn it on using the
ON/OFF switch on the front panel. The power inverter is now ready to deliver AC power to your loads. If you are operating several loads from the power inverter, turn them on separately after the inverter has been turned on. This will ensure that the power inverter does not have to deliver the starting currents for all the loads at once.
1. Controls and indicators
The ON/OFF switch turns the control circuit in the power inverter on and off. It does not disconnect power from the power inverter.
When the switch is in the OFF position, the power inverter draws no current from battery. When the switch is in the ON position but with no load, the power inverter draws less than 450mA
(12V version) or 300 mA (24V version) from battery.
2. Battery voltage indicator
The battery voltage graph indicates the voltage at the input terminals of the power inverter. At low input current, this voltage is very close to the battery voltage. At high input current, this voltage will be lower than the battery voltage because of the voltage drop across the cable and connections.
Ideally, the voltage should remain in the green area of the bar graph. If the voltage goes into the red area at top and bottom of the graph, inverter may shutdown.
-Do not operate high power loads with the power inverter while watching television.
-Make sure that the antenna feeding your television provides an adequate ("snow free") signal and that you are using good quality cable between the antenna and the television.
-Move the television as far away from the power inverter as possible.
-Keep the cables between the battery and the power inverter as short as possible and twist them together with about 2 to 3 twists per foot. This minimizes radiated interference from the cables.
3. Load percentage indicator
The load watts grap indicates the watts of the appliances you use.
If the load goes into the red area at top,inverter may shut down.
2.Troubleshooting guide
Problem possible cause solution
4. Overtemp indicator
The overtemp indicator indicates that the power inverter has shut itself down because it is overheated. The power inverter may overheat because it has been operated at power levels above its rating, or because it has been installed in a location which does not allow it to dissipate heat properly.
Please turn on the inverter again when it cools down.

Low battery alarm Battery volt is low Charge battery
Operating limits
1. Input voltage
The power inverter will operate from input voltage ranging 10V-15V (12V ver.) or 20V - 30V (24V ver.).
If the voltage drops below 10.0V (12V ver.) or
20.0V (24V ver.), an audible low battery warning will sound and the voltage indicator will be in the lower red zone.
The power inverter will shut down if the input voltage drops below 10V (12V ve.) or
20V (24V ver.). This protects your battery from being over discharged.
The power inverter will also shut down if the input voltages exceed 15V (12V ver.) or 30V (24V ve.).
This protects the inverter against excessive input voltage indicator will be in the upper red zone.
Although the power inverter incorporates protection against over voltage, it may still be damaged if the input voltage is allowed to exceed 20V (12V ver.) or 40V (24V ver.).
※ The error of above spec is ±0.5V
Maintenance
Very little maintenance is required to keep your inverter operating properly. You should clean the exterior of the unit periodically to prevent accumulation of dust and dirt. At the same time, tighten the screws on the DC input terminals.

Troubleshooting
1. Common problems a.
Buzz in audio systems:
Some inexpensive stereo systems and "boom boxes" will emit a buzzing noise from their loudspeakers when operated from the power inverter. This is because the power supply in the device does not adequately filter the modified sine wave produced by the power inverter.
The only solution is to use a sound system that incorporates a higher quality power supply.
b.
Television interference:
Operation of the power inverter can interfere with television reception on some channels. If this situation occurs, the following steps may help to alleviate the problem.
-Make sure that the chassis ground lug on the back of the power inverter is solidly connected to the ground system of your vehicle, boat or home.
